Not unless you're interested in a Starving Student. Too many people could not build the T3 (I repaired several of them). There are just too many pratfalls in a DIY kit where investment > $1K. I used to lose sleep over PupDAC customers when basic PCB investment in parts was $75 and they could not get the PCM 2707 and 1794 soldered correctly. However, we're very close to having production ready for the T4 (not a kit).
